TEF 4900 Fused flasher module
TEF 4900 Fused flasher module
TEF 4900 Commander series.
Fused flasher module with current detection.
Designed for switching and flashing of signal lights. Status of light is
monitored by a build-in current detector. Delivered for 115/230V lamps.

Features
- DIN rail mounting.
- 2-pole switching. Both poles fused.
- Zero-cross switching
- Build-in current detection to determine if output circuits are OK or not.
- Lamp circuit galvanic isolated from control circuit.
- Connections for main and emergency supply to output circuit.
- Build-in snubber network which allows termination of a wide range of communication cable, 100-250ohm characteristic impedance. End resistors shall not be used.
- Current detection can be disabled if a particular system does not require this feature. This may be done in software configuration or as a direct setting on the module
- The module may also be set locally to manually adjust flashing pattern.
Certificates
- Tested according to IEC60945:2002
- Approved by Det Norske Veritas (DNV).
